Introduction: There are few longitudinal male cohort studies with serial assessments of growth and puberty.Objective: To describe the design and implementation of a longitudinal cohort study of Russian boys evaluated annually for growth, development and puberty.Design/methods: We assembled a multi-disciplinary team of U.S. and Russian researchers to design and conduct a longitudinal boys’ cohort study in Chapaevsk, Russia with...

Background: We are not aware of other longitudinal cohort studies of boys with annual assessments of pubertal development and long term follow-up to adulthood to evaluate semen quality.Objective: To describe semen quality and investigate its predictors in a longitudinal cohort study of Russian boys followed from prepuberty until adulthood.Design and methods: From 2003 to 2005, 516 prepubertal 8–9-year-old boys were enrolled (8...

Background: We are not aware of other longitudinal cohort studies of boys with prepubertal assessment of exposure to endocrine-disrupting chemicals (EDCs) and annual long term follow-up of growth and puberty to evaluate semen quality.Objective: To describe semen quality and explore associations of prepubertal serum concentrations of organochlorine compounds and pubertal measures with semen parameters in an ongoing longitudinal cohort study of Russian boy...

It has been recognized for over 20 years that there is an association between patterns of early growth and long-term risk of traditionally adult onset diseases such as type 2 diabetes. This has been observed both in human epidemiological studies and in animal models. This led to the concept of the developmental origins of health and disease that suggests that the environment to which an individual is exposed during critical periods of development, such as the in utero...

Background: ‘D’ was a 7 year old Caucasian female who presented with a history of adult-type body odour starting at age 3 years. At age 6y 9m her bone age was 7y 10m. She had had a sharp increase in her weight in the past 2 years and her PCP noticed pubic hair growth. Her very anxious single mother was convinced she had a serious illness that needed immediate intervention.Case presentation: At presentation, D had Tanner 2 pubic hair and Tanner ...

Background: The association between Turner syndrome and Type1/ Type 2 diabetes is well known. Growth hormone is also utilized in Turner syndrome to improve height outcomes, but association of Turner patients with growth hormone deficiency is rare. To my knowledge, there are no cases of concurring Turner syndrome, Type 1 diabetes, and growth hormone deficiency.Objectives: To describe a rare case where a child diagnosed wi...

TN was seen in India aged 7 years by her GP, with concerns about tall stature and increase in belly fat. She had a family history of diabetes, high cholesterol and early deaths. Her mother has diabetes, a round face and prominent limb musculature with very little subcutaneous fat. TN was investigated by a paediatric endocrinologist in India. Tests showed high triglycerides and insulin levels at the upper level of normal for her age. She was put on a strict diet and exercise pr...

Childhood-onset growth hormone deficiency (CO-GHD) is topical at present due to the increasing understanding of underlying genetic aetiologies, influence on childhood growth, and future effects on adolescence and adult health. There is no previous Irish data of this group of children.Methods: A retrospective cohort study over 2 years (2013-2015) including all children diagnosed with GHD who received recombinant growth hormone treatment (rGH). Predictors ...

Background: CO-GHD can be caused by a variety of aetiologies, including pituitary or brain structural abnormalities, and increasingly recognised genetic mutations of pituitary transcription factors. Idiopathic GHD is a diagnosis of exclusion. POU1FI is a late pituitary transcription factor. Mutations of POU1F1 have autosomal recessive (AR) inheritance, and phenotypically present with a normal or small anterior pituitary gland on magnetic resonance imaging (MRI), they are assoc...

Background: Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue. Cardinal features affect cardiovascular system, eyes and skeleton. It is caused by mutations of FBN1 gene, which encodes the extracellular matrix protein fibrillin 1. The improper activation of TGFβ, due to defective fibrillin-1, is the pathophysiological mechanism. The altered modulation leads to overgrowth of long bones (disproportionate stature) and altered bone morphology.<p ...
